Definitions

  • the present invention relates to a process for producing a high-purity sphingomyelin, in particular, a human sphingomyelin, and a high-purity plasmalogen-form glycerophospholipid, which are useful as materials of functional foods, medicinal products, cosmetics etc., from a biological material, preferably from poultry, by simple procedures at high yields.
  • Lipids refer to substances that have a long-chain fatty acid or similar hydrocarbon chain in a molecule, and that are present in an organ or derived from a zoic organ. Lipids can be classified into simple lipids and complex lipids. Simple lipids are composed of C, H and O, and are generally soluble in acetone; the simple lipid triacylglycerol is present as an energy reservoir in a fat tissue of an animal body. On the other hand, complex lipids are a group of lipids containing P of phosphoric acid, N of a base etc. Therefore, complex lipids are composed of a hydrophobic part (fatty acid part) and a hydrophilic part (phosphoric acid and base parts), and exhibit an amphophilic nature. Generally, the above simple lipids are soluble in acetone, while the complex lipids are insoluble in acetone. Such complex lipids are a constituent of biomembranes.
  • the above complex lipids can be classified into (1) glycerophospholipids (such as phosphatidylcholine (also known as lecithin), phosphatidylethanolamine, etc.), (2) sphingophospholipids (such as sphingomyelin, ceramide ciliatine, etc.), (3) sphingoglycolipids (such as cerebroside, sulfatide, ganglioside, etc.) and (4) glyceroglycolipids (such as lipids in which various saccharides bond to diacyl glycerol existing in microorganisms or higher plants).
  • the above (2) sphingophospholipids and (3) sphingoglycolipids are generically referred to as "sphingolipids".
  • the above glycerophospholipid is a generic term for lipids having glycerophosphoric acid backbone in their structure, and includes phosphatidylcholine (lecithin), phosphatidylethanolamine, diphosphatidylglycerol, etc.
  • Many lipids belonging to this glycerophospholipid are those in which the non-polar portion is a fatty acid ester, while some are of a plasmalogen form having a vinyl ether bond.
  • the above glycerophospholid is important as a constituent of biomembranes; above all, the plasmalogen-form glycerophospholipid has high radical sensitivity due to its vinyl-ether bond, and, hence, in recent years has been highlighted as a phospholipid having anti-oxidation nature. It has recently been reported that the plasmalogen-form glycerophospholipid contributes to oxidation-stability of phospholipid membrane containing cholesterol through a mechanism different from ⁇ -tocopherol (vitamin E) that is an anti-oxidation constituent of cell membrane (for example, see Non-patent Literature 1).
  • vitamin E ⁇ -tocopherol
  • Non-patent Literature 2 the plasmalogen-form glycerophospholipid not only takes part in the oxidation resistance of cell membrane and lipoprotein, but also has an important role in the information communication system of cells (for example, see Non-patent Literature 2).
  • the above plasmalogen-form glycerophospholipid is expected to have the function of preventing the death of brain nerve cells in dementia. Under the circumstances, however, no supply source that is safe and makes a large amount available has been found.
  • sphingolipid is a generic term for lipids having a long-chain base such as sphingosine, and it is composed mainly of sphingoglycolipid and sphlngophospholipid as described above.
  • the sphingoglycolipid contains a long-chain base such as sphingosine, phytosphingosine etc. in addition to saccharide and long-chain fatty acid.
  • sphingoglycolipid The simplest sphingoglycolipid is cerebroside; apart from cerebroside, sphingoglycolipid includes sulfatide in which a sulfuric acid group is bonded thereto, ceramide oligohexoside in which several molecules of neutral saccharide are bonded thereto, ganglioside in which sialic acid is bonded thereto, etc. These lipids are present in the cell cortex, and are thought to take part in a recognitive mechanism.
  • Sphingophospholipids are classified into derivatives of ceramide 1-phosphoric acid and derivatives of ceramide 1-phosphonic acid.
  • Sphingomyelin is a well-known example of the former, while ceramide ciliatine (ceramide aminoethylphosphonic acid) is a well-known example of the latter.
  • sphingolipids are highlighted since it has been shown in recent years that ceramide, sphingosine, sphingosine-1-phosphoric acid, etc., which are decomposition metabolites thereof, take part in the information communication in cells. Further, sphingolipids take part in the formation of a membrane microdomain called a "raft" together with cholesterol, etc., and it has been shown that this microdomain plays an important role as a site of information communication; accordingly, further increased attention has been paid to sphingolipids.
  • sphingolipids have hitherto been extracted from cow brains and utilized; however, those that are derived from cereals or fungi are now used from a safety standpoint. Since, however, sphingoid bases constituting sphingolipids derived from cereals or fungi differ from those of mammals, there is a problem that their utility in organisms is low compared with human-form sphingolipids.
  • sphingomyelin when a relatively large amount of sphingomyelin is produced from total lipids of foods or animal tissues, it is produced by eluting it stepwise by means of column chromatography using silicic acid, etc., or by fractionating it stepwise according to a solvent fractionation method. Both of these require complicated procedures.
  • solvent fractionation method it is a general practice to employ a method in which acetone is added to total lipids to precipitate complex lipid (phospholipid) (insoluble portion), after which the insoluble portion is washed with ether to remove glycerophospholipid, and the residue is taken as a crude sphingolipid fraction.
  • This fraction contains not only sphingomyelin, but also glycerosphingolipids such as cerebroside.
  • the phospholipid of chicken skin contains a great deal of human-form sphingomyelin and plasmalogen-form glycerophospholipid.
  • J. Am. Oil Chem. Soc., vol. 85, 2008, pages 427 to 433 discloses a concentration method of complex lipids from the skin of mature laying hens. Therein, the complex lipids are separated from an ethanol extract of minced skin by solvent fractionation with a hexane/ethanol system.
  • an object of the present invention is to provide a process for producing high-purity sphingomyelin, in particular, a human sphingomyelin, and high-purity plasmalogen-form glycerophospholipid from a biological material by simple procedures at high yields.
  • the present inventors conducted intensive studies to achieve the foregoing object, and found that the above object can be achieved by processing a biological material in a specific manner. Based on this finding, the inventors completed the present invention.

  • the present invention provides a process for producing high-purity sphingomyelin, in particular, human sphingomyelin, and high-purity plasmalogen-form glycerophospholipid, which are useful as materials of functional foods, medicinal products, cosmetics etc., from a biological material, preferably from poultry, by simple procedures at high yields; generally a high-purity sphingomyelin and a high-purity plasmalogen-form glycerophospholipid is obtained by the process.
  • the process for producing high-purity phospholipid according to the present invention comprises Step (A), Step (B), Step (C), Step (D) and Step (E).
  • This Step (A) is a step in which the dried total lipids extracted from a biological material are subjected to extraction treatment with a mixture solution of an aliphatic hydrocarbon solvent and a water-soluble ketone solvent to separate an insoluble portion composed mainly of sphingomyelin and a soluble portion.
  • the biological material used as a raw material in Step (A) is not particularly limited, and various biological materials may be used as long as they contain a sphingomyelin, in particular, a human sphingomyelin, and a plasmalogen-form glycerophospholipid.
  • various biological materials poultry is preferable in terms of its availability, content of target substance, and economical efficiency; further, culled laying hens and culled breeding hens of broilers (male/female) are more preferable. Examples of regions include bowel, neck, wing, leg, head, bone, etc., as well as epidermis and breast.
  • the aforementioned culled laying hens refer to laying hens subjected to culling. Culling is performed, for example, by fasting white strain laying hens (Julia) or brown strain laying hens (Boris Brown, Sonia) for several days at an average age of 550 days old.
  • those subjected to forced molting are particularly preferred for the following reasons.
  • Forced molting is performed by fasting laying hens of about 500 and several days old, which have decreased laying efficiency, for 10 to 14 days, and then compulsorily de-feathering the hens. This process reproduces the functions of the laying hen, thereby prolonging the laying period by about another 200 days. These forced-molted laying hens are culled in the same way as above.
  • these forced-molted laying hens are subjected to another forced molting at about 700 days old, thereby further extending the laying period by up to 900 days (this period is referred to as double forced molting).
  • An appropriate time of culling of the laying hens is at 500 to 950 days old, more preferably 550 to 900 days old, further preferably 600 to 750 days old.
  • the laying hens in particular, those of 500 days old or older, are under greater stress than the other hens. Therefore, as evident from the described function reproduction shown by the increase in laying efficiency, the secretions of various function-expressing components, such as minor components including hormones, vitamins and cytokines, whose contents are decreased in aged hens, increase, thereby preventing the decrease of the contents by aging.
  • various function-expressing components such as minor components including hormones, vitamins and cytokines, whose contents are decreased in aged hens, increase, thereby preventing the decrease of the contents by aging.
  • broiler breeding hens male/female Chunky and Cobb
